[Detailed description of the invention]

[0001]

[Industrial application field] The present invention relates to an electric connection between a moving body and a fixed side.
The present invention relates to a wiring structure of a wire harness for air connection .

[0002]

2. Description of the Related Art Conventionally, a wire harness c provided between a moving body a and a fixed side b has a flat shape as shown in FIG.
Form and wraps the intermediate arcuately, Japanese Utility Model 57-4
Protecting with a flexible guide cylinder disclosed in Japanese Patent Publication No. 9984
ing. In addition, the minimum radius of curvature R 'of the wire harness d installed may be secured at the closest position between the moving body a and the fixed side b (FIG. 6B), or the wire harness e may be secured.
Is spirally wound to increase the spiral diameter φ to some extent (FIG. 6C).

[0003]

However, in the case of FIG. 6A, the radius of curvature R of the wire harness c is determined.
Not only requires a large space S for holding,
A guide for guiding the moving folded portion is required, which increases the cost. In addition, of Japanese Utility Model Publication No. 57-49984
In such a case, the cost of the flexible guide cylinder is high. Further, FIG.
In the case of (b), it is necessary to provide an interval of 2R 'between the moving body a at the closest position and the fixed side b. FIG.
In the case of (c), the spiral wire harness e moves in the moving direction.
It must be provided between the spacing L for preventing wrap the moving body a and the fixed side b, to be secured to another broad construction for space and space for movement with a conventional example of any of the above There is a problem that it does not. The present invention has been made in order to solve the above problems, and does not require a large space for erection, and is locally deformed.
It is an object of the present invention to provide a wiring structure of a wire harness having high durability without being disconnected .

[0004]

As a specific means for achieving the above object, a reciprocating moving body is connected to a wire harness.
The wire harness is electrically connected to the fixed
A bent part is formed in the middle part of the
A spring property is provided between the bent portion and the movable body and the fixed side.
Position each of the supporting plates to the outside of the wire harness.
And the wire harness is attached through these attachment plates.
The bent part of the ties with a binding band
Then, attach the free ends of the both attachment plates to the moving body and the fixed side.
Wiring of wire harness characterized by being fixed respectively
A structure is provided.

[0005]

The operation of the wiring structure of the wire harness is as follows. The wiring harness is disconnected by moving the moving object.
From the part bound by the bundle band, open both sides on the left and right like open legs. At this time, the attachment plate should be
Bent between the fixing portion of the side, but the curved at a moderate curvature without bending their bent portion by the spring elasticity of the served plate. When the moving body approaches the fixed side, the wire harness is closed by the spring resilience of the attachment plate, and the right and left sides of the wiring harness finally come into close contact with each other.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described with reference to the drawings. FIG. 1 is a perspective view of a wire harness wiring structure according to the present invention, and FIG. 2 is a sectional view of the same. Wire harness 2 summarizes the power lines and signal lines is coated over substantially the entire length by inserting a plastic tube 3 of the cross section is flattened flexible, bending Ri folding in clamshell-like at its substantially intermediate portion. Left and right wire harnesses 2a,
Long attachment plates 5 and 5 having spring elasticity are inserted between the outer surfaces 2b and 2b of the 2a and the vinyl tube 3, respectively.

[0007] The subscript plate 5,5, tip 5a, 5a is inserted up to in fold bent portion 6 of each of the wire harness 2. Further, two screw holes 5b, 5b are provided at free ends of the attachment plates 5, 5 projecting from the openings 4, 4 of the vinyl tube 3. As haunting the in fold bending portion 6 is opened, the bent portion via a served plate 5,5
6 for binding by the binding band 7. Vinyl tube 3
The wire harness 2 and the attachment plates 5 and 5 are also bound by the binding bands 8 and 8 at the left and right ends of the wire harness 2 so that the attachment plates 5 and 5 do not shift in the vinyl tube 3.

[0008] Then, screwing holes 5b subscript plate 5,5 of the left and right as shown in FIGS. 3 and 4, the 5b, mobile 11
And fixed to the corresponding side surfaces 11a and 12a of the fixed side 12 with screws 9,9. Here, the moving body 11 includes, for example, a self-propelled robot or an automatic door , and the fixed side 12 includes, for example, a control box for controlling the robot or the automatic door, but is not limited thereto. Both ends of the wire harness 2 are connected to terminal boxes (not shown).

Next, the operation of the wire harness wiring structure will be described. When the moving body 11 moves and separates from the fixed side 12, the wire harness 2 is bound by the binding band 7.
It bends at the part and opens to the left and right. Wire harness 2
Are attached plates 5, 5 whose bent portions 6 have spring elasticity.
Are bound by the binding band 7 through the
Has its free ends screwed to the movable body 11 and the fixed side 12, respectively . For this reason, the moving body 11 moves and
Also open ear harness 2 is to open leg-like, served with plates 5, 5 of the bar
Due to the elasticity, it does not bend at the binding position but bends at an appropriate radius of curvature r. Similarly, the screwing portions on the movable body 11 and the fixed side 12 also bend with an appropriate radius of curvature r '(FIG. 5A). On the other hand, when the moving body 11 moves to and approaches the fixed side 12, the curved portion of the wire harness 2 that is opened to the left and right becomes linear due to the spring resilience of the attachment plates 5 and 5, and the left and right sides are closed and adhered ( FIG. 5 (b)).

The wiring harness wiring structure of the above embodiment is
Even if the moving object repeats reciprocating movement, it
Nest 2 does not bend and wire
Disconnection of the harness 2 can be prevented. Further, when the moving body 11 moves to the fixed side 12, the moving body 11 opens right and left from the bent portion 6.
And in the wire harness 2 is brought into close contact, the wire harness 2
It can be stored in the space of two. Since the attachment plates 5 and 5 are fixed to the movable body 11 and the fixed side 12, the lateral swing of the wire harness 1 during movement can be reduced.
There is an advantage that there is no need to guide using a guide, and the cost is low. In the above embodiment, the vinyl tube 3
The attachment plates 5 and 5 were inserted into the
It may be attached.

[0011]

As described above, the present invention has the above-described structure, and the movement of the moving body allows the wire harness to be connected to the binding bun.
Open the bundling portion by de the open leg shape to the left and right curved at a moderate curvature without bending locally by the spring elasticity subscript plate, the moving body approaches the fixed-side wire harness with it is served plate It is closed by the spring elasticity of the wire harness, so that the finally bent left and right wire harnesses are in close contact, even if the moving body repeats reciprocating movement,
It does not bend locally and does not break due to aging. Also, since not required in addition to extensive room for a wire harness laid in the moving space of the moving body, there are excellent effects such as the optimum as a wiring structure of a wire harness to be bridged between the mobile and the fixed-side .
